Filed: 1991-03-29
Abstract: PURPOSE:To reduce power loss in a current detecting resistor while preventing erroneous function of an overcurrent protective circuit due to noise by connecting a current transformer, secondary winding thereof has higher number of turns than that of the primary winding, to the output side of a transformer. CONSTITUTION:A current transformer 24, secondary winding of which has higher number of turns than that of the primary winding, is connected in series with a line between the secondary winding of a transformer 3 and a smoothing circuit 5. Secondary current of the current transformer 24 is then subjected to half-wave rectification through a diode 25 and fed to an output current detecting resistor 26 in order to detect a half-wave voltage proportional to the peak value of output current Io. When the output current increases and the voltage at the inverted input terminal of a differential amplifier 9 reaches a reference voltage at the non-inverted input terminal to cause voltage drop at the output of the differential amplifier 9, a transistor 22 feeds a reset current to a saturable reactor 7 through a diode 23. Consequently, output voltage is restricted so that the output current does not increase thus realizing overcurrent protection.

Title: Life diagnosis for battery of uninterruptible power supply
Inventor: OKAZAKI KOJI
IPC: H02J7/34
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To diagnose accurately the life of the battery of an uninterruptible power supply without stopping power supply to a load. SOLUTION: With DC voltage VDC outputted from a converter circuit 2 made roughly equivalent to discharge voltage VBT of a battery 4, discharge voltage VBT of the batery 4 is obtained from the output voltage V1 of the converter circuit 2 at that time. At the same time, the discharge current IBT of the battery 4 is obtained from the current I1 flowing from the battery 4 to an inverter circuit 3. Then, the period for which the battery 4 can discharge is obtained from a graph of these voltage V1, current I1, and discharge characteristics of the battery 4 to determine the life of the battery 4. As a result, it is not necessary to stop the converter circuit 2 at the time of diagnosing the life of the battery 4. It is thus possible to diagnose the life of the battery 4 of the uninterruptible power supply accurately without stopping power supply to a load 5.

Title: Composition for separating serum or plasma
Inventor: AYAKA HISAMI
IPC: G01N33/48
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To suppress the extent of flow or phase separation significantly even after long time preservation by adding dicyclopentadien resin and silica having -CO absorption intensity of infrared absorption spectrum within a specified range of -CH absorption intensity. SOLUTION: A dicyclopentadien resin having -CO (about 1745 cm<-1> ) absorption intensity of infrared absorption spectrum in the range of 2-20% of -CH (about 2839 cm<-1> ) absorption intensity is employed. It means dicyclopentadien resin oxidized to some extent. Since silica is bonded to the oxidized part of dicyclopentadien resin to bring about a cross-linked state, an optimal cross- linked state can be realized by limiting the oxidized part of dicyclopentadien resin within a range to be discussed. Consequently, the bonding power between dicyclopentadien resin and silica is increased and the extent of flow or phase separation of a composition thus produced for separating serum or plasma can be suppressed significantly even after long time preservation.

Title: Diaphragm for speaker
Inventor: INOUE TOSHIHIDE
IPC: H04R7/02
Filed: 1990-04-03
Abstract: PURPOSE:To make high stiffness and large internal loss compatible with each other by using a compound of liquid crystal high polymer fibers and thermoplastic synthetic resin fibers. CONSTITUTION:A diaphragm of a speaker is made of liquid crystal high polymer fibers and thermoplastic synthetic resin fibers and the liquid crystal high polymer fibers are linked and made composite by the molten thermoplastic synthetic resin fibers at heat molding. Since the density (rho) of the liquid crystal high polymer fibers is small and its tensile strength is large and its melting point is high, then the liquid crystal high polymer fibers are stable thermally, and the fibers have fibril structure, the internal loss (tanbeta) of the fibers themselves is large. When the liquid crystal high polymer fibers are made composite by the molten thermoplastic synthetic resin fibers, the liquid crystal high polymer fibers are uniformly dispersed in the composite, and the density (rho) of the composite is small and the tandelta is high. Thus, high stiffness and large internal loss are made compatible.

Abstract: PURPOSE: To make forging of a metal material forging of poor hot workability easy by pouring a metal material of poor hot workability into a mold made of steel  plates, covering the upper and lower parts thereof by steel plates after freezing then  subjecting the same to heating and forging.  
     CONSTITUTION: A mold 1 made of steel plates is set on the bed plate 4 on a molding board 5 provided with a cross gate 6, and a head heat-insulating plate 3 is disposed in the upper part of its inside surface. Metal of poor hot workability such as high alloy steel or special alloy is cast through the cross gate 6 by bottom pouring from a pouring pipe 7. In this case, the thickness of the steel plate 1 for the mold is suitably selected depending upon the static pressure and temperature of the molten metal 2 to be cast and the shape of the mold 1 is made into a shape close to the one resembling to a forged shape. When the cast metal has frozen, it is cut from the bottom and the bottom and head of the cast ingot 9 are covered by steel plates 8, 8 which are then welded to the mold steel plate 1. Next, the ingot is heated to its forging temperature and is forged. The cast ingot 9 to be forged causes less temperature drop owing to the presence of the steel plates 1, 8 of the surroundings and permits long-time forging; in addition, the surface of the cast ingot 9 is less cracked.
